Diffusion Index

Has anyone created a diffusion type index? I am looking to use the Breadth function in Optuma but I need to create a combination of an advance decline line and a percent of constituents indicator so I was looking to see if anyone had a created something similar in which to model against.

Hi Duke,

As the diffusion index is an AD line on the %up breadth measure we can just Accumulate the difference in that value.

You can do this in a ShowView tool.

// first get the breadth data (whether you build it or get one of the breadth tickers)
B1 = GetData(code={BREADTH TICKER});

// now we get the difference from yesterday
D1 = B1 - B1[1];

// then accumulate it for the result

Hope that helps
